1. ATR 72-100 (The Analog Pioneer)
- Cockpit: Pure 1980s analog/steam gauges.
- Powerplant: P&WC PW124 (2,160 SHP / 2,400 SHP OEI) with 4-blade Hamilton Standard 14SF-11 propellers.
- Key Sim Dynamics: Highly limited by thermal performance and lower weights (MTOW: 19,990 kg). It requires significant runway length (1,510 m) and precise engine management.
2. ATR 72-200 (The Mass-Production Workhorse)
- Cockpit: Analog.
- Powerplant: Upgraded P&WC PW124B (2,160 SHP / 2,400 SHP Max Continuous) with 4-blade propellers.
- Key Sim Dynamics: Increased structural capacity (MTOW: 21,500 kg) and better continuous climb power. The pilar of 1990s regional aviation.
3. ATR 72-210 (The "Unicorn" Hot & High Hybrid)
- Cockpit: Early digital transition hybrid (primitives EFIS screens for navigation/flight instruments, combined with analog engine clocks).
- Powerplant: P&WC PW124BM (2,400 SHP / 2,750 SHP OEI Boost).
- Key Sim Dynamics: Only two real units operated this specific setup (including the legendary, long-lived EC-KAD / ex EC-IPJ still flying in 2026 for Swiftair as a Quick-Change Combi!). It features a massive electronic power boost for emergency/high-altitude operations but suffers cruise degradation ("clogging") past FL140.
4. ATR 72-210A / Early -500 (The 4-Blade Upgrate)
- Cockpit: Advanced LCD/EFIS cabin.
- Powerplant: Shift to the modern P&WC PW127 series (2,475 SHP / 2,750 SHP OEI) but retaining the 4-blade Hamilton Standard 247F-1 propellers.
- Key Sim Dynamics: Excellent airfield performance (Take-off distance drops to 1,211 m) with the higher torque of the modern engine combined with 4-blade aerodynamics.
5. ATR 72-500 / 212A (The Ultimate Classic)
- Cockpit: Full modern corporate regional glass layout.
- Powerplant: P&WC PW127F/M driving the iconic 6-blade Hamilton Standard 568F propellers.
- Key Sim Dynamics: Massive structural ceiling, completely redefined cabin acoustic simulation, and MTOW up to 22,000+ kg.
📂 Attached Technical Specs (Pages 15 to 21)
I have attached the technical sheets detailing exact dimensions, certified weights (MTOW, MLW, MZFW), takeoff/landing speeds ($V_2$, $V_{ref}$), airfield performance lengths, and en-route fuel flow data for each specific variant.
Whether this sparks interest for a dedicated Freeware/Open-Source community group, or catches the eye of established Payware developers like Just Flight, Black Square, or iniBuilds looking for their next hardcore turboprop project... the blueprints are ready.
Let’s bring the analog ATR family to life! What are your thoughts?
